Now with more coherency.

All of human knowledge in my inbox?

After doing some manual restoration of emails from one user to another in DB
Mail I suddenly found that the estimated usage was quite
large. Approximately 17 exabytes (an exabyte is 1024 petabytes, which is 1024
terabytes, which is 1024 gigabytes).

And the compression must be pretty good too, after all it is fitting on a
volume only 200 gigabytes in size!

Unfortunately I’m guessing this is a bug in how it updates quotas. Pity, it
would make up for UQ rejecting my request for access
to the library (which I just found out you should be able to get for the first
twelve months after you graduate).
